# Always Sometimes Never for Absolute Value, Opposite, Reciprocal, and Opposite Reciprocal

Post Contents

Monday, we are starting our first unit of Algebra 1 by looking at the definitions of absolute value, opposite, reciprocal, and opposite reciprocal. Last year, I made the mistaken assumption that my 9th graders would be proficient at finding the absolute value of a number/expression when they came in. In addition to absolute value, Iâ€™ve decided to address opposites, reciprocals, and opposite reciprocals at the same time. This should save us some time when we get to discussing perpendicular lines!

I decided to create an Always/Sometimes/Never activity to get my students thinking about these terms at a deeper level.

Hereâ€™s what I came up with:

Iâ€™ve currently got a set of tents in the works for a clothesline activity to go with this lesson.

I am also curious about this… I have seen lots of ideas for clothesline math, but haven't found any directions as to how it is organized. ??? Thanks for sharing your resources!
